Hi there!
x > 0.073171.
Why?
First to solve we need to add 30x to both sides of the inequality.
-9.5x - 1.5 + 30x > -30x + 30x
20.5x - 1.5 > 0
Next we need to add 1.5 to both sides.
20.5x - 1.5 + 1.5 > 0 + 1.5
20.5x > 1.5
Finally, divide both sides by 20.5.
20.5x/20.5 > 1.5/20.5
x > 0.073171
So our answer is x > 0.073171.
Hope this helps!

Answer:
10n
Step-by-step explanation:
n represents number, its like using X, since we don't have the information on it, we replace it with a letter.
Answer:125
Step-by-step explanation:
The correct option is B): "<span>Let x = 1st integer. Let x + 2 = 2nd integer.</span><span>"
Given that "The sum of two consecutive odd integers is 28."
Now the difference between two odd numbers is 2.
So this means that one odd number has to be greater than the other by 2.
Let the smaller number be 'X' therefore the bigger number will be 'x+2'
thus
x + (x+2) = 28
therefore,
x + x + 2 = 28
now we subtract "2" from both the sides
therefore,
2x = 26
now dividing throughout by 2 we get:
x = 13
therefore,
x + 2 = 13+2
= 15
therefore, the numbers are
13 AND 15</span>
